Abstract
An off axis hydraulic pump for an automatic motor vehicle transmission includes an integrated chain and sprocket assembly. A first, chain drive sprocket is mounted on a shaft driven by an input to a torque converter and a second, driven chain sprocket is attached to a stub shaft which drives the pump. A multi-link chain encircles the sprockets and transfers drive torque from the torque converter input to the stub shaft. The first, chain drive sprocket is retained on the input shaft by a retainer cap which includes seals between both the shaft and a torque converter housing. The second, driven chain sprocket is retained on the stub shaft by a snap ring or similar component.
